Optimising germanium hole spin qubits with a room-temperature magnet
Cecile X. Yu, Barnaby van Straaten, Alexander S. Ivlev +6
Germanium spin qubits exhibit strong spin-orbit interaction, which allow for high-fidelity qubit control, but also provide a strong dependence on the magnetic field. Superconductin…
A two-dimensional 10-qubit array in germanium with robust and localised qubit control
Valentin John, Cécile X. Yu, Barnaby van Straaten +10
Quantum computers require the systematic operation of qubits with high fidelity. For holes in germanium, the spin-orbit interaction allows for \textit{in situ} electric fast and hi…
Exploiting epitaxial strained germanium for scaling low noise spin qubits at the micron-scale
Lucas E. A. Stehouwer, Cécile X. Yu, Barnaby van Straaten +10
Disorder in the heterogeneous material stack of semiconductor spin qubit systems introduces noise that compromises quantum information processing, posing a challenge to coherently…
A spinless spin qubit
Maximilian Rimbach-Russ, Valentin John, Barnaby van Straaten +1
All-electrical baseband control of qubits facilitates scaling up quantum processors by removing issues of crosstalk and heat generation. In semiconductor quantum dots, this is enab…
